LOCK-NUT AN D BOLT.

SPECIFICATION forming part of Letters Patent No. 777,085, dated December 13, 1904.

Application filer. December 4, 1903.

To all whom it may concern.-

Be it known that I, JOHN R. ELDER, a citizen of the United States, residing at Columbus, in the county of Franklin and State of Ohio, have invented a certain new and useful Improvement in Lock-Nuts and Bolts, of which the following is a specification.

My invention relates to the improvement of lock-nuts; and the objects of my invention are to provide an improved lock-nut for bolts which will obviate the necessity of forming screw-threads on the bolt and by means of which a secure and reliable connection of the nut and bolt may be produced, to provide an improved nut construction, and to produce other improvements the details of construction of which will be more fully pointed out hereinafter. These objects I accomplish in the manner illustrated in the accompanying drawings, in which Figure 1 is a transverse section of a rail- Way-track rail having my improved nut-locking device in connection therewith, the latter being shown in elevation. Fig. 2 is a side elevation of portions of two rails employing my improved lock-nut. Fig. 3 is a transverse section on line w of Fig. 2. Fig. 4 is a plan View of two adjoining members connected by a bolt having my improved lock-nut and showa modified construction and use of said nut, and Fig. 5 is a detail view in elevation of the locking-key which I employ in the manner hereinafter set forth.

Similar numerals refer to similar parts throughout the several views.

In carrying out my invention I employ a bolt, such as isindicated at 1, said bolt having formed in its periphery adjacent to its outer end an elongated recess 2, the bolt-stem being otherwise smooth and unthreaded.

3 represents my improved nut-body, which is in the nature of a metallic block, as shown, and which has formed through its upper portion a rectangulr opening 4. Extending through the nut-body at right angles with the direction of the opening 4 is an unthreaded bolt-hole 5, the latter being so located with reference to the opening 4 as to extend partially within or intersect longitudinally said Serial No. 183,723. (No model.)

opening 4. When my improved nut-lock is designed for use in connection with rail-uniting bolts of railway-tracks or for similar use where the bodies to be united are provided with inclined flanged bases or fish-plates, I form the lower side of the nut-body on an incline, so that the greater height of the nut is on its outer side.

In order to illustrate the use of my improved nut, I will first describe the same-as applied to railway-track rails and fish-plates, such as are indicated, respectively, at 6 and 7. The bolt is inserted through the web of the rail and the fish-plates in the usual manner, and the outer projecting end of the boltis inserted within the opening L of the nut, the rear and shorter face of the latter being adapted to abut against the adjoining fish-plate. This being accomplished, a wedge-shaped split key, such as is indicated at 8 in Fig. 5 of the drawings, isinsertcd horizontally through the opening 4 of the nut and recess 2 of the bolt, said key being driven therein between the inner side of the opening 4 and the outer side of the recess 2, thus forcing the bolt outward and tightening the nut against the adjoining fish-plate, with the result that the iislrplates are drawn tightly in connection with the web of the rail. If desired, one of the outer ends of the wedge shaped key 8 may now be turned outward to in sure its retention in the locked position.

In Fig. 4 of the drawings I have shown my improved lock-nut and key in connection with a belt, which is shown as uniting two bodies other than railway-track rails, which I have numbered as 9 and 10. It will be understood that in this use the necessity of inclining the under side of the nut is obviated and, if desired, the nut may be so turned that the key 8 may be inserted vertically, as shown in Fig. 4:, instead of horizontally.

By the construction and operation herein shown and described it will be understood that a simple, reliable, and effective lock-nut and bolt construction is provided which will obviate the necessity of providing the bolt and 95 nut with engaging threads and which will insure the retention of two bolt-engaged members in desirable contact with each other. It

Will be understood that where my improved device is utilized in connection with railwaytrack joints the inclined base of the nut will contact with and conform to the usual inclined base-flange of the adjoining fish-plate and that the construction of my improved lock-nut is such as to obviate any tendency of the parts of the same becoming separated through jar or vibration.

Having now fully described my invention. What I claim, and desire to secure by Letters Patent, is

In a lock-nut and bolt, the combination with.

an unthreaded bolt having a transverse channel-W ay form ed therein, of a nut provided with an unthreaded bolt-hole and having an opening therethrough contained wholly within the same and disposed at right angles to the length of the bolt-hole, intersecting the said bolt-hole in its periphery, and a wedge-shaped split key to fit in the channel-way of the bolt and the transverse opening through the nut.
